SerialElement and preloading DynamicStreaming

Question

HI,
We are trying to create a solution where each video is prefixed by a 5 seconds videoBumper intro, that is defined upfront not ad-served.
The videos are all using dynamicstreaming and the bumper is a simple video.
We are using a SerialElement adn trying to use a preload function (with play/pause) to achieve smooth transition between the bumper and the real video.
Preload works ok for the normal video but for the Dynamic streaming for some reason it create an issue: when the player reaches the dynamicstreaming video it continue to play until the end but the video player shows no video = black screen.
I don't understand why it doesn't work.
Any idea?

Thanks Brian,
Please find the code below - "res" is the dynamic streaming smil loaded - please note that if i remove the preload calls everything works.
   var resource:URLResource = new URLResource(new FMSURL('rtmp://cp67126.edgefcs.net/ondemand/mediapm/strobe/content/test/SpaceAloneHD_sounas_640_5 00_short'));
var kvFacet:KeyValueFacet = new KeyValueFacet(MetadataNamespaces.SUBCLIP_METADATA);
kvFacet.addValue(MetadataNamespaces.SUBCLIP_START_ID, 0);
kvFacet.addValue(MetadataNamespaces.SUBCLIP_END_ID, 5);
resource.metadata.addFacet(kvFacet);
bumperElement = new VideoElement(new NetLoader(), resource);
preload(bumperElement);
mediaElement = new VideoElement(new DynamicStreamingNetLoader(), res);
mediaElement.addEventListener(MediaErrorEvent.MEDIA_ERROR, onMediaError);
preload(mediaElement);
serialElement = new SerialElement();
serialElement.addChild(bumperElement);
serialElement.addChild(mediaElement);
     function preload(mediaElement:MediaElement):void
var loadTrait:LoadTrait = mediaElement.getTrait(MediaTraitType.LOAD) as LoadTrait;
loadTrait.addEventListener(LoadEvent.LOAD_STATE_CHANGE, onLoadStateChange2);
loadTrait.load();
function onLoadStateChange2(event:LoadEvent):void
if (event.loadState == LoadState.READY)
loadTrait.removeEventListener(LoadEvent.LOAD_STATE_CHANGE, onLoadStateChange2);
var playTrait:PlayTrait = mediaElement.getTrait(MediaTraitType.PLAY) as PlayTrait;
playTrait.play();
playTrait.pause();
wrapper.element = serialElement;
wrapper.mediaPlayer.autoPlay = true;
